Description

The maximum total amount of memory that can be occupied by result set caches across concurrent connections. Values must be specified in: B (bytes), KB (kilobytes), MB (megabytes), or GB (gigabytes).

For example, when this property is set to the default value of 200MB, if you have 3 concurrent Impala connections, the total amount of memory consumed by the 3 result set caches for those connections cannot exceed 200MB.

These result set caches are used only when query retries are enabled. For more information about this feature, see Enable Query Retry.

For information about setting a maximum cache size for the current connection only, see Result Set Cache Size.
